[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
(Embodiment 1)
[Description of configuration]
FIG. 1 is a schematic configuration diagram of a version upgrade system according to an embodiment of the present invention. FIG. 1 shows a portable telephone terminal 100 such as a PDC / CDMA / PHS portable telephone, an external storage device 110 such as an SD / MMC card storing a plurality of new software of the portable telephone terminal 100, A connection bus 105 such as an SD / MMC card bus for connecting these, and a password owned by, for example, a mobile phone carrier and used to execute version upgrade prior to version upgrade in the mobile phone terminal 100 and the external storage device 110 And an authentication device 200 that performs the creation of a password.
[0019]
The mobile phone terminal 100 includes a built-in nonvolatile memory 102 storing mobile phone software 103 and boot start-up software 104, a receiving unit 106 for receiving a password transmitted from the authentication device 200, and an operation of the main body of the mobile phone terminal 100. And a CPU 101 for program-controlling the program.
[0020]
The external storage device 110 stores new mobile phone software 111, which is upgrade software for the mobile phone terminal 100.
[0021]
Here, the boot start-up program (reading means) 104 determines whether the external storage device 110 is connected to the main body of the mobile phone terminal 100 and determines whether the new mobile phone software 111 is stored in the external storage device 110. Determining whether the password received in advance is the same as the password stored in the new mobile phone software 111, determining whether the new mobile phone software 111 is for a required version upgrade, It rewrites the telephone software 103.
[0022]
The authentication device 200 includes a creation unit 201 that creates a password for executing the version upgrade in the mobile phone terminal 100 and the external storage device 110 prior to the version upgrade, and a portable device that copies the password created by the creation unit 201 prior to the version upgrade. It comprises a transmitting means 202 for transmitting to the telephone terminal 100 and a storing means 203 for storing the password created by the creating means 201 in the new mobile phone software 111.
[0023]
[Description of operation]
Next, the operation of the version upgrade system of FIG. 1 will be described.
[0024]
FIG. 2 is a flowchart showing the operation of the version upgrade system of FIG.
[0025]
First, the authentication device 200 creates a unique password by the creation unit 201 based on transmission of information indicating software for which version upgrade is desired from the mobile phone terminal 100 side and a distribution request of the external storage device 110, and transmits the password. It outputs to the means 202 and the storage means 203 in parallel.
[0026]
This password is a password for taking out version-up software for software desired to be version-upd from a plurality of version-up softwares, and also serves as a password for permitting version-up.
[0027]
The transmitting unit 202 transmits the password output from the creating unit 201 to the mobile phone terminal 100 by radio waves via the telephone network.
[0028]
The mobile phone terminal 100 receives the password transmitted from the transmitting unit 202 by the receiving unit 106 and outputs the password to the boot start-up software 104.
[0029]
On the other hand, the storage unit 203 stores the password output from the creation unit 201 in the new mobile phone software 111 for upgrading the mobile phone terminal 100.
[0030]
The external storage device 110 including a plurality of new mobile phone software 111 in which a password is stored is mailed to the mobile phone terminal 100 side or passed through a mobile phone terminal store or the like.
[0031]
The user of the mobile phone terminal 100 receiving the external storage device 110 connects the external storage device 110 to the mobile phone terminal 100 via the connection bus 105.
[0032]
Next, when the user turns on the power of the mobile phone terminal 100 in this state (step S1), the CPU 101 executes the boot startup software 104 to initialize the connection bus 105 (step S2).
[0033]
Next, the boot startup software 104 determines whether the external storage device 110 is connected beyond the connection bus 105 (step S3).
[0034]
Here, since the external storage device 110 is connected, the boot startup software 104 determines whether or not the external storage device 110 stores a plurality of new mobile phone software 111 (step S4).
[0035]
If the external storage device 110 is not connected, the boot startup software 104 notifies the CPU 101 of the fact, and the CPU 101 activates the mobile phone software 103 (step S8).
[0036]
If the new mobile phone software 111 is stored, the boot startup software 104 determines whether the password previously received and output to the CPU 101 is the same as the password stored in the new mobile phone software 111. Do.
[0037]
If the result of the determination is that the passwords do not match, the authentication is not successful and the version upgrade process is stopped. If the passwords match, it is determined whether the new mobile phone software 111 for the software whose version is desired to be upgraded among the plurality of new mobile phone softwares 111 is newer than the mobile phone software 103 and is for the required version upgrade. A determination is made for confirmation.
[0038]
If the result of the determination is that the new mobile phone software 111 is not for the required version upgrade, the version upgrade process is stopped. If the new mobile phone software 111 is for a required version upgrade, the mobile phone software 103 is deleted from the built-in nonvolatile memory 102 (step S5).
[0039]
Further, the boot startup software 104 stores the new mobile phone software 111 in the built-in nonvolatile memory 102 (Step S6).
[0040]
Finally, the boot start-up software 104 starts the new mobile phone software 111 stored in the built-in nonvolatile memory 102 (step S7).
[0041]
【The invention's effect】
As described above, according to the present invention, both the user and the mobile phone carrier can conveniently upgrade the software.
[0042]
In particular, according to the present invention, on the side of the business operator, for example, only preparing an external storage device storing all the upgraded software, only the required one of the plurality of upgraded software is stored on the mobile phone terminal side. Since it is possible to take out the software, it is not necessary to prepare an external storage device storing a plurality of version-up software in various combinations.
